WILLIAM A. BORDEN AD CLAUDIUS H. M. ROBERTS, OF THE UNITED STATES ARMY.

BOMB' BODY.

Application led June 27, 1922. Serial No. 571,223.

(FILED UNDER THE ACT F MARCH 3, 1883, 22 STAT. L., 625.)

Be it known that we, "ILLIAM A. BORDEN, major, Ordnance Department,United States Army, and CLAUDiUs H. M. ROBERTS, captain, OrdnanceDepartment, United States Army, citizens of the United States, stationedat lVashington, District of Columbia, have invented an Improvement in aBomb Body, of which the following is a specification.

The invention described herein may be v used by the Government, or anyof its Ofticers or employees in prosecution of work for the Government,O1' by any other person in the United States, without payment to us ofany royalty thereon, in accordance with the act of March 3, 1883.

The subject of this invention is a bomb and the invention relates morespecifically to the construction of a bomb body. In the construction ofa bomb body it is necessary that the body be so designed that it willassume a proper position during flight; that it possesses rigidity: thatit is susceptible ofquantity production andthat the parts of the bodymay be easily and readily assembled.

The present invention has been devised to accomplish these desiredresult-s, specifically, by providing a body of drawn tubing to which thenose and base may be easily attached orwhich may be spun or swaged toform a nose.

lith these and other objects in view, which will hereinafter more fullyappear, the invention resides in the novel arrangement and combinationof parts and in the details of construction hereinafter described andclaimed, it being understood that changes in the precise embodiment ofthe invention herein disclosed may be made within the lscope of what isclaimed Without departing from the spirit of the invention.

Practical embodiments of our invention are illustrated in theaccompanying drawings, wherein:

Fig. 1 is a view in side elevation of a bomb constructed in accordancewith our invention;

Fig. 2 .is an enlarged detailed View in longitudinal section of the noseand a fragment of the body;

Fig. 3-x }is a section on the line 3-3 of Fig. 2;

Fig. et is a fragmentary view in side elevation, partly in section, ofthe base and tin assembly of the bomb;

Figs. 5, 6 and 7 are sections on the lines 5; 6-6; and 7-7, respectivelyof Fig. 4;

Fig. 8 is a longitudinal section of a moditied form of bomb body;

Fig. 9 is a fragmentary detail sectional view of the base and adapter;

Fig. 10 is a similar view of the structure for locking the base cap inplace;

Fig. 11 is a sectional view of the carrying lug, showing a fragment ofthe body to which it is attached;

Fig. 12 is a view in elevation of the lug.

In carrying out our invention we prefer to provide a body 10 of drawntubing, convenientlysteel, to the forward end of which is attached thenose piece 11. A desirable form of attachment, as herein shown, isprovided by reducing the end of the nose piece, as indicated at 12, Fig.2, so that the same may telescope within the forward end of the body 1()and the parts then connected together by welding as at 13, and furthersecured by rivets 14 passed through the telescoping portions which aredrilled or other! wise apertured for that purpose.

The forward end of the nose piece is adapted to receive an adapter 15 towhich a booster 16 may be connected and the forward end of which hasconnection with a bearing member 17 in which the fuse mechanism isjournaled and which may be snpplied with eyes 18 for the reception ofthe end of a safety wire 18.

The rear end of the body 10 is closed by a base plug 19 which telescopesinto the rear end of the body and which may be welded thereto asindicated at 20.

The base plug is preferably formed with a slightly tapered, rearwardlyextending, annular flange 21 to provide a seat for a purpose hereinafterset forth, and it is also cent-rally apertured and tapped to receive anadapter 22 to the inner end of which may be connected a booster 23 andtO the outerend of which is connected a tubular rod 24.

The tubular rod acts as a. housing for the base fuse mechanism and hasits outer end threaded to receive a nut 25 which engages the rear end ofa base cap 26 the forward end of which cap embraces the tapered flange21, to hold the cap firmly in place. The base cap has connected theretothe stabilizers or fins 27.

The base cap 26 is preferably made up of a single sheet rolled to form acone and the meeting edges butt welded. Angle pieces 28 are connected bywelding or riveting or both to the cap and between them the inner vedgesof the stabilizers or fins are secured. When, as illustrated herein, thefins extend for a considerable distance to the rear of the base cap,such extending portions may be bound together by angle pieces 29 whichare laced in the angles formed at adjoining e ges of adjacent fins andare securely bound together upon the fins by riveting. The fins may befurther secured against exure or distortion by braces 30 which extenddiagonally between adjacent fins to which they are connected in anysuitable manner as by riveting.

For the purpose of hanging bombs from the carrier or rack of anaircraft, a lug or lugs 3l ma be provided. These lugs are to be attac edto the body in the field and to provide a ready attachment of theselugsthe body is tapped as at 32 for the reception of studs` 33, havingheads 34 formed with reduced necks 34. In order that undue strain maynot be placed upon the parts when the lugs are attached, due to the useof too large a wrench or the like, the necks 34 are sufficiently reducedin thickness to cause them to shear when a strain in excess of thatcalculated is applied. The tapped apertures 32 may be convenientlyclosed at their inner ends by a plate 35 which is welded or otherwisesecured to the interior face of the body thus protecting the explosivecontained in the body from exposure.

The base fuse casing 36 may be properly located and held within the tube24 by inea-ns of a tubular plug 37 which is forced into the rear end ofthe body and encircles the casing.

In the modified form shown in Fig. R, the body 10 is drawn to a tube andthe forward end is spunv or swaged to form the nose 11 which isapertured at 38 and tapped for the reception of an adapter or closureplug. The base and fin assembly are assembled to this form of body asheretofore described in relation to the preferred form.
